Question 1

Which vertex should be the second one in a topological sorting of the following DAG?

1 / 1 point

a

b

c

d

e

Correct

Indeed, the first vertex in a topological sorting of this DAG should be c, as the only one with no incoming edges. Next, b should follow as the second one. Actually, this DAG has two topological sortings: c, b, a, e, d and c, b, e, a, d.
